Only devices which make contact with the conductor ie not proximity devices should be used for proving dead. If you are unsure as to what test leads you need to use, speak to our technical team on While it has fundamentally remained the same as the previous version, there are some key additions that could affect the way you test, or the equipment you are using. Is hs page useful?

This is an important safety issue as using equipment that is not correctly rated for the installation category can and has resulted in serious injury and death. Specific requirements for test leads In line with changes made to the standards that cover the manufacture of test leads, there are some specific requirements that leads should comply with added in the fourth edition: If you find you have leads or test equipment that no longer meet these requirements, or have been damaged, it would be advisable to replace them to ensure your ongoing safety.

This fourth edition includes current test equipment and references and links to further guidance have been updated. This has a new paragraph added regarding the use of non-contact detectors, or volt sticks: You can visit our cookie privacy page for more information.

Throughout this section, revisions have been made yse include the need for ongoing risk assessments to ensure safety is maintained as well as re-emphasis of the need for selecting the right CAT safety rating for the installation under test. Provided your existing equipment or leads meet either of the above there should be no need to replace anything until they need it.

Setting the multimeter to the wrong voltage range will lead to a false reading, but having it set to measure current or resistance can result in excessive current being drawn through the test probes, leads and multimeter.

When it comes to buying new voltage detectors, you can be sure compliance with GS38 if the unit you are buying complies to BS EN Firstly the Guidance Note has been amended ys38 reflect relevant changes to the standard for two pole voltage indicators, BS EN See also Electrical safety at work Safe maintenance Risk management The health and safety toolbox – how to control risks at work.

A nse has been added to clarify that live working is defined as any testing or fault finding on live systems. However, non-contact or proximity devices can be useful in indicating if something is live, eg when attempting to remove a single cable installed in trunking containing many single cables.

For loop impedance, RCD or multifunction testers, the fuse will typically be 10A. For existing leads and equipment predating these standards, or manufactured to a different standard, GS38 states they must be maintained to prevent danger and should comply with the guidance probes and clips in paragraph 9 download the full guidance note below.

This standard, which came into full effect in Mayis the standard that all new two pole voltage indicators should comply with. Health and Safety Executive.
